When a honey bee hive is exposed to localized heat stress, adult bees shield baby bees (the brood) by positioning themselves between the heat source and the brood. These "heat shielders" then absorb the excess heat, protecting the brood from a rise in temperature that would be detrimental to development. Where do the heat shielders go to cool themselves off? We used thermal imaging to find out!
